Method and Device for Wireless Signal Transmission or Reception in Wireless Communication System

2. The method according to claim 1, wherein based that information regarding a number of PDCCH candidates in the PDCCH SS configuration indicates ‘M’, ‘M’ monitoring candidates are assigned per the CORESET frequency region of each SB.

3. The method according to claim 2, wherein the wireless communication device performs the detection of the PDCCH within ‘k’בM’ PDCCH candidates, without assigning a monitoring candidate to an SB in which the CORESET frequency region is not configured in the BWP, where ‘k’ denotes a number of SBs in which the CORESET frequency region is configured.

4. The method according to claim 1, wherein, based on a same value ‘M’, the wireless communication device determines, in respective CORESET frequency resource region configured in each of a first SB and a second SB, resources of monitoring candidates for a corresponding aggregation level, where ‘M denotes a number of the monitoring candidates for the corresponding aggregation level indicated by the PDCCH SS configuration.

5. The method according to claim 1, wherein the BWP operates in an unlicensed cell (UCell).

6. The method according to claim 1, wherein the SBs are frequency bands for which listen-before-talk (LBT) is performed.

7. The method according to claim 1, wherein a same SS is configured in the CORESET frequency region of each SB.

8. A non-transitory medium readable by a processor and recorded thereon instructions that cause the processor to perform the method according to claim 1.

11. The apparatus of claim 9, wherein the apparatus is an application specific integrated circuit (ASIC) or a digital signal processing device.

13. The method according to claim 12, wherein based that information regarding a number of PDCCH candidates in the PDCCH SS configuration indicates ‘M’, ‘M’ PDCCH candidates are assigned per the CORESET frequency region of each SB.
